September Seminar
Inorganic QD Photoresist for Next-Gen Energy Efficient Displays
September 26, 2024
Presentation Abstract
MicroLED display technology is in a period of rapid technological development and different architectures are being evaluated to fit a wide range of market applications from microdisplays to video walls. In particular, color converted architectures using quantum dots have been proposed to enable ease of manufacturing as compared to RGB displays assembled from direct emitting LEDs. InGaN and AlGaInP have been proposed for direct emitting red microLEDs, while quantum dot conversion of red by InP quantum dots has been proposed from both blue and UV InGaN LEDs. Efficiency, color gamut and resolution are critical factors in choosing a microLED architecture. We have modeled the efficiency tradeoffs of these architectures based on a meta-analysis of literature data in combination with experimental results as a function of pixel size. The color gamut of direct and color converted architectures are also calculated from our meta-analysis of literature data, and advantages of different architectures are demonstrated. Potential issues with integration of quantum dots in microLEDs will be discussed, in particular optical absorption strength, efficiency, patterning resolution, and reliability. Mitigation paths to address the challenges of quantum dot integration will be demonstrated with the use of NanoPattern’s proprietary quantum dot photoresist.

Victor is currently working with several high-tech companies, focusing on business development, sales, and fundraising. At NS Nanotech, he leads the Biz Dev and Sales team, securing licensing deals for next-generation Group III-Nitride (InGaN) RGB nanowire LEDs, which are crucial for micro displays used in AR/XR applications. He’s also pioneering the launch and sale of the world’s first solid-state Far-UVC Emitter. In addition to his work at NS Nanotech, Victor serves as a BD Advisor for Cellid, a Japanese AR startup that is advancing DOE Wave Guides for the next generation of AR glasses. Victor’s passion for the display industry spans from tiny micro displays to large, wall-sized displays. He has experience with a range of technologies, from QD-enabled LCDs and OLED displays to the latest in microLED displays. Throughout his career, Victor has held several executive roles. As VP of Biz Dev for Orthogonal, he drove OEM adoption for a novel fluorinated photoresist system capable of patterning ultra-high PPI AMOLED displays with up to 90% fill-factor, which was recently licensed to Samsung. He has also served as VP of Worldwide Sales and Marketing for Nanosys, supplying Quantum Dots to the display industry. Victor is also deeply involved in the Society for Information Display (BASID), where he currently serves as Chair of Corporate Communications for the Bay Area chapter. In this role, he helps secure speakers for the monthly BA-SID meetings, contributing to the ongoing dialogue in the
display industry.
